Chromebooks let you personalize your screen with images stored on your device. Changing the wallpaper from Files takes seconds and makes your computer feel more personal. The Files app gives you direct access to any picture saved on your Chromebook.
You can use photos you downloaded, screenshots you captured, or images transferred from other devices. This method works faster than browsing through pre-installed themes. Your selected image appears immediately without extra steps or confirmations needed.
How to Change the Wallpaper on a Chromebook From Files?
The Files app offers the quickest way to set a custom wallpaper on your Chromebook. You access your stored images directly and apply them in two clicks.
Open the Files Application
Click the launcher button on the left side of your taskbar. The launcher icon looks like a circle with dots inside. Select Files from the menu that appears.

Navigate to Your Image Location
Browse through your folders to find the picture you want. Check your Downloads folder for recently saved images. Look in the My files section for screenshots or photos you transferred.

Apply Your Selected Image
Right-click directly on the image file you chose. Select “Set as wallpaper” from the menu. Your screen background changes instantly to display the selected picture.

Alternative Desktop Method
Right-click any empty space on your desktop. Choose “Set wallpaper” from the options. Scroll to the bottom of the left panel and click “My images.” This displays all compatible pictures stored on your device.
Use Compatible Image Formats
Your Chromebook accepts PNG and JPG files for wallpapers. GIF and BMP formats won’t work and may cause display errors. Convert incompatible images before setting them as backgrounds.
Sync Across Multiple Devices
Click the clock icon in the lower right corner of your screen. Select the gear icon to open Settings. Go to Personalization and find “Sync and Google services.” Enable “Theme & Wallpaper” to apply your wallpaper choice across all your signed-in Chromebooks.
Many users encounter restrictions in school or work environments. Administrators sometimes disable wallpaper changes through device management policies. Contact your IT department if the right-click option doesn’t appear or changes won’t save.
You can bypass some desktop restrictions by accessing Settings directly. Open Settings from the system tray. Navigate to the Personalization section. This method works when right-click functionality is disabled on your device.
